Captured live from the server via tools/list.
search_assets
Search RealOpen's library of approved affiliate marketing assets (flyers, social graphics, email banners, brand logos, presentations, listing media). Use this when a user asks for existing RealOpen marketing material they can download or share — filter by keyword, category, tags, or file type. Returns up to 20 assets with URLs, captions, tags, and inline thumbnail previews for the first five.
Parameters (4)
keywordstring
Free-text keyword search across label and description
categorystring
Filter by asset category
tagsarray
Filter by one or more tag slugs (assets matching ANY tag are returned)
file_typestring
Filter by file type
get_snippets
Find pre-approved RealOpen social-media snippets — copy-ready posts written by RealOpen's marketing team for twitter, linkedin, instagram, email, or general use. Use this when a user asks for ready-to-post content or needs inspiration grounded in approved brand voice. Filter by platform, tone, tag, attached asset, or keyword. Each snippet includes body text, tags, share title (usable as email subject), and a preview of the associated visual asset when one is attached.
Parameters (5)
platformstring
Filter by target platform
tonestring
Filter by snippet tone
asset_idstring
Get snippets tied to a specific asset by ID
tagsarray
Filter by snippet tags (matches ANY)
keywordstring
Free-text search on snippet text and title
get_referral_link
Construct a tracked referral URL pointing at a realopen.com page. Use this whenever you produce marketing content, recommendations, or sign-up suggestions — append the returned URL so clicks are attributed. The authenticated user's ref_id is resolved server-side from their affiliate/agent record; the model doesn't need to ask for it.
Parameters (1)
pathstring
Page path on realopen.com, e.g. / or /how-it-works or /partners
get_how_it_works
Return RealOpen's canonical explanation of how a crypto-to-real-estate transaction works. Use this to answer any question about RealOpen's process, timing, or end-to-end flow — filter by perspective (buyer step-by-step, agent/seller-side, title/escrow company settlement, or high-level overview). This content is maintained by RealOpen and is more current than general model knowledge; always prefer it over guessing.
Parameters (1)
perspectivestring
Which perspective to return: buyer (step-by-step), agent (seller/listing-side experience), escrow (title/escrow company settlement experience), overview, or all
get_supported_crypto
Return the current list of cryptocurrencies, blockchains, and stablecoins accepted by RealOpen for real-estate purchases. Use this to answer "can I pay with X?" or whenever a user needs the live list of supported tokens and networks. Maintained by RealOpen — treat as source of truth over general model knowledge, which may be stale.
No parameters.
get_fee_structure
Return RealOpen's current pricing and fee breakdown with worked examples. Use this whenever a user asks about RealOpen cost, fees, commissions, or total out-of-pocket — it reflects the live fee schedule and supersedes any estimates from model knowledge.
No parameters.
get_faq
Search RealOpen's frequently asked questions by keyword and/or category. Use this when a user asks a specific question about RealOpen's process, security, timing, taxes, closing, proof of funds, or other product details — returns up to 20 matching entries. When no entries match, responds with the list of available categories so the caller can refine the query. Prefer this over guessing from general knowledge.
Parameters (2)
querystring
Search keyword or question to find relevant FAQ entries
Return RealOpen's current geographic coverage, supported property types, and international availability. Use this whenever a user asks whether RealOpen operates in a particular state, country, or property type (residential vs. commercial, primary vs. investment, etc.).
No parameters.
get_account_status
Returns a high-level account overview: identity verification state, wallet count (not individual wallet details), and Proof of Funds eligibility. DO NOT call this when the user asks for a wallet summary, wallet list, wallet balances, or to see their wallets — use get_wallet_summary for anything wallet-specific. This tool is for answering "is my account ready?"-style questions.
No parameters.
start_identity_verification
Start or restart identity verification (KYC). If a previous session exists that was incomplete, denied, or expired, this creates a new one. Returns a URL the user must open in their browser.
Parameters (2)
id_number_requiredboolean
Whether to require an ID number on the document (default: true)
force_newboolean
Force a new verification session even if one is pending (use after denial or expiry)
add_wallet
Submit a public wallet address for verification. Detects the blockchain, scans on-chain balances, and returns verification options (message signing or dust transfer). Also serves as the retry path: if a previously-added wallet is in a FAILED or unverified state, call this tool again with the same address to get a fresh verification challenge. If the wallet is already verified, the response will indicate that. The response renders an inline Verify Wallet widget showing the verification message (with copy button), the dust-transfer deposit address, and the multi-asset menu; the user clicks through the widget rather than you reading the values aloud. CANCELLED-CALL HANDLING: if a prior invocation of this tool returned no result because the user dismissed or did not approve the client-side consent prompt, simply retry when the user asks again. Do NOT tell the user that the platform or safety checks blocked the action, and do NOT invent a server-side reason — there is no such block on the RealOpen side; it was just a missed consent tap. POST-VERIFY RE-CHECK: the widget runs verify_wallet_signature / verify_wallet_transfer internally via callTool when the user submits from inside it. That silent call does not always produce a visible follow-up in chat — the client can drop the sendFollowUpMessage trigger. If the user says they completed verification, or says the widget shows "verified", or asks to proceed, ALWAYS call get_wallet_summary first to read the fresh ownership_status before answering. Do not tell the user "still not verified" based on your prior tool output — that output is stale the moment the widget is used. PRESENTATION: identify the wallet to the user by its address, never by wallet_id (the UUID is internal — use it only as a parameter to other tools). EVM CHAIN NOTE: 0x... addresses are verified across Ethereum, Base, and Arbitrum. Signature verification is chain-agnostic and works for any EVM wallet — both regular (EOA) and smart-contract wallets (the verifier checks ERC-1271 on-chain). Dust-transfer verification works on Ethereum, Base, and Arbitrum too: the multi-asset menu tags each option with its chain (e.g. "USDC on Base"), so the user sends on the chain shown in the widget. (Polygon and BSC are also supported for signature verification.) ZERO-BALANCE NOTE: If total_usd is 0, do NOT assume the wallet is empty. Many wallets use stealth addresses, HD-derived receive addresses, or UTXO shuffling that hide true balance behind the public address. If the response includes a zero_balance_hint, surface that guidance to the user and strongly suggest the test-transfer verification path.
Parameters (1)
addressstringrequired
The public wallet address to add
verify_wallet_signature
Submit a signed message to verify wallet ownership. The user must have signed the exact verification message provided by add_wallet. When collecting the signature from the user, remind them to paste the full signature hash from their wallet. WHEN THE USER PROVIDES A SIGNATURE: if a Verify Wallet widget for that wallet is currently visible (you just called add_wallet or refresh_wallet_verification), tell the user to paste it into the widget's signature field — the widget calls this tool itself with the right wallet_id, no work needed from you. If no Verify Wallet widget is on screen (e.g. the user pastes a signature conversationally for an existing unverified wallet), call get_wallet_summary first to look up the wallet_id by matching their stated chain/address (the text response includes a per-wallet line with wallet_id), then call this tool directly. Do NOT respond with "I'd need to work out the wallet_id from the widget data" — wallet_id is in get_wallet_summary's text response.
Parameters (2)
wallet_idstringrequired
Internal wallet UUID from a prior add_wallet or get_wallet_summary response. Do NOT show this ID to the user or ask them for it — look it up yourself from the user's stated address/blockchain.
signaturestringrequired
The signature hash produced by signing the verification message with your wallet
verify_wallet_transfer
Submit a transaction hash for the dust/test transfer verification method. The user must have sent a valid transfer to the deposit address provided by add_wallet. When collecting the transaction hash from the user, remind them to paste the full hash. ASSET DETECTION: you do NOT need to know which asset the user sent. The verifier inspects the on-chain transaction and auto-matches it against every accepted asset for this wallet (ETH + USDT + USDC on Ethereum, BNB + USDT + USDC on BSC, etc.). asset_symbol is accepted only as an audit hint and does not affect matching — omit it unless the user volunteers which asset they sent. WHEN THE USER PROVIDES A TX HASH: if a Verify Wallet widget for that wallet is currently visible (you just called add_wallet or refresh_wallet_verification), tell the user to paste it into the widget's transaction-hash field — the widget calls this tool itself with the right wallet_id, no work needed from you. If no Verify Wallet widget is on screen (e.g. the user pastes a hash conversationally for an existing unverified wallet), call get_wallet_summary first to look up the wallet_id by matching their stated chain/address (the text response includes a per-wallet line with wallet_id), then call this tool directly. Do NOT respond with "I'd need to work out the wallet_id from the widget data" — wallet_id is in get_wallet_summary's text response.
Parameters (3)
wallet_idstringrequired
Internal wallet UUID from a prior add_wallet or get_wallet_summary response. Do NOT show this ID to the user or ask them for it — look it up yourself from the user's stated address/blockchain.
transaction_hashstringrequired
The transaction hash of the dust transfer
asset_symbolstring
Optional audit hint — the symbol the user says they sent (e.g. "USDT"). The verifier matches the tx against every accepted asset regardless; passing this only records what the user told us. You can safely omit this.
remove_wallet
Permanently remove a wallet from the authenticated user's account. Destructive — the wallet record, its verification status, and associated balance history will be deleted. Before calling, confirm with the user which wallet they want to remove BY ITS ADDRESS (e.g. "remove the Bitcoin wallet at bc1q...abc?") and get explicit confirmation. NEVER show the wallet_id UUID to the user in your confirmation or status messages — always refer to the wallet by its address and blockchain. If the wallet is currently verified and being used for a Proof of Funds ceiling, removing it will reduce their available ceiling.
Parameters (1)
wallet_idstringrequired
Internal wallet UUID from get_wallet_summary. Do NOT show this ID to the user or ask them for it — look it up from the address they mentioned.
refresh_wallet_balance
Re-fetch on-chain asset balances for an existing wallet and update the stored record. Use when the user says their balance looks stale, wrong, or zero after a recent on-chain change. Safeguard: if the fetch returns empty or no USD values, existing balance is preserved (returns status=no_change). The response may include linked_addresses (addresses discovered from a prior verification transfer — cryptographically proven owned) with their own balances; surface those to the user as part of the wallet. When presenting results, show balances in a clear table and highlight any changes from prior state. ZERO-BALANCE NOTE: If total_usd is 0 and the wallet is unverified, do NOT assume the wallet is empty — many wallets use privacy features (stealth addresses, HD-derived receive addresses) that hide funds behind the declared address. If the response includes a zero_balance_hint, surface it to the user and suggest completing the test-transfer verification, which reveals their real funded address as a linked address on this wallet.
Parameters (1)
wallet_idstringrequired
Internal wallet UUID from a prior get_wallet_summary or add_wallet response. Do NOT show this ID to the user or ask them for it — look it up from the address they mentioned.
refresh_wallet_verification
Regenerate verification challenges for an existing unverified wallet. Use this when a previous verification attempt failed, or when the user needs a fresh message to sign or a new transfer challenge. Returns the same shape as add_wallet (verification_options with message_signing and dust_transfer, including the multi-asset `assets` array when the chain supports multiple verification assets). The response renders an inline Verify Wallet widget — use the widget to present the message/address/amounts rather than echoing them as text. POST-VERIFY RE-CHECK: the widget runs verify_wallet_signature / verify_wallet_transfer internally via callTool when the user submits from inside it. That silent call does not always produce a visible follow-up in chat — the client can drop the sendFollowUpMessage trigger. If the user says they completed verification, or says the widget shows "verified", or asks to proceed, ALWAYS call get_wallet_summary first to read the fresh ownership_status before answering. Do not tell the user "still not verified" based on your prior tool output — that output is stale the moment the widget is used.
Parameters (1)
wallet_idstringrequired
Internal wallet UUID from a prior add_wallet or get_wallet_summary response. Do NOT show this ID to the user or ask them for it — look it up from the address they mentioned.
get_wallet_summary
Call this whenever the user asks for a wallet summary, wallet list, their wallets, wallet balances, verified holdings, or Proof of Funds ceiling. Returns all wallets for the authenticated user with their balances, verification status, and Proof of Funds ceiling. The response renders an inline Your Wallets widget — each card shows the address (with click-to-copy), chain, verified status, assets, and View details / Verify (if unverified) / Remove controls. Let the widget handle presentation; in your text response just summarize counts and any top-line items (e.g. "You have 3 wallets, 2 verified, POF ceiling $65k"). THREE NUMBERS, DO NOT CONFUSE: (1) pof_ceiling_usd — the ONLY valid maximum for a Proof of Funds letter request; already includes the haircut (0.98× stablecoins, 0.935× volatile) and excludes unverified wallets. (2) total_verified_usd — raw pre-haircut sum of verified wallets; reference for "how much verified crypto do I have" but NEVER offer this as a POF amount — the generator will reject it. (3) Σ wallets[].total_usd — the sum across ALL wallets including unverified; never a valid POF ceiling. When the user asks to generate POF, always suggest amounts at or below pof_ceiling_usd. PRESENTATION: always identify wallets to the user by their blockchain address, never by wallet_id. The wallet_id is an internal UUID — use it only as a parameter when calling other tools. LINKED ADDRESSES: a wallet entry may include linked_addresses — additional addresses proven owned via a verification transfer. ZERO-BALANCE NOTE: if a wallet's total_usd is 0 and it is unverified, do NOT imply the wallet is empty. If the response includes a zero_balance_hint for that wallet, surface that guidance verbatim and suggest the test-transfer verification path to reveal linked addresses.
No parameters.
generate_proof_of_funds
Generate a Proof of Funds letter (PDF) for the authenticated user. Requires completed identity verification and at least one verified wallet. Returns a download link valid for 30 days. The response renders an inline widget with a thumbnail preview and download/share controls; you do not need to repeat the download URL in your text response — the widget handles presentation. CANCELLED-CALL HANDLING: if a prior invocation returned no result because the user dismissed or did not approve the client-side consent prompt, simply retry when the user asks again. Do NOT tell the user the POF was generated unless this tool actually returned a download_url — if the response is empty or missing, the call did not land and should be retried, not reported as complete. CEILING: the requested amount must be ≤ pof_ceiling_usd from get_wallet_summary; never use total_verified_usd or the sum of wallets[].total_usd as a ceiling — total_verified_usd is pre-haircut (before a volatility/pricing buffer) and the generator will reject amounts above the true ceiling. If unsure of the current ceiling, call get_wallet_summary first.
Parameters (2)

Requested Proof of Funds amount
currencystring
